Embodiment 1
[0044] The invention provides a method for intelligently adjusting the brightness of an electronic exterior rearview mirror of an automobile, which is used to adjust the brightness of the interior screens of the electronic exterior rearview mirrors on both sides of the driver, such as figure 1 shown, including:
[0045] Step S1, collecting the facial image of the driver in real time;
[0046] Step S2, judge the driver's face orientation based on the face image, and adjust the brightness of the screen in the car according to the driver's face orientation:
[0047] Step S3a, in response to judging that the driver's face is facing forward, adjusting the brightness of the in-vehicle screens on both sides of the driver to a first preset brightness;
[0048] Step S3b, in response to judging that the driver's face is facing to the left, adjust the brightness of the in-vehicle screen on the left side of the driver to a second preset brightness, and the second preset brightness is gre...
Embodiment 2
[0062] The present invention also provides an intelligent adjustment device for the brightness of the electronic exterior rearview mirror of an automobile, such as figure 2 As shown, it is used to implement the brightness intelligent adjustment method in the above embodiment, including:
[0063] The interior screens of the two electronic exterior mirrors ( figure 2 The shown screen A, screen B), are respectively arranged on the left and right sides of the driver;
[0064] The first acquisition module 1 is used to collect the facial image of the driver in real time;
[0065] The first judging module 2 is connected to the first collecting module 1, and is used to judge the driver's face orientation based on the facial image;
[0066] The brightness adjustment module 3 is connected to the first judgment module 2 and two in-vehicle screens respectively, and is used to adjust the brightness of the in-vehicle screen according to the driver's face orientation:
[0067] In respon...

Abstract
The invention relates to the technical field of automobile control systems, in particular to an intelligent brightness adjusting method and device for an automobile electronic outside rear-view mirror, and the method comprises the steps: collecting a face image of a driver in real time; judging the face orientation of the driver based on the face image, and adjusting the brightness of the in-vehicle screen according to the face orientation of the driver: in response to judging that the face of the driver faces forwards, adjusting the brightness of the in-vehicle screen on two sides of the driver to first preset brightness; in response to the judgment that the face of the driver faces the left side, adjusting the brightness of the in-vehicle screen on the left side of the driver to second preset brightness, wherein the second preset brightness is greater than the first preset brightness; in response to the judgment that the face of the driver faces the right side, adjusting the brightness of the in-vehicle screen on the right side of the driver to third preset brightness, wherein the third preset brightness is greater than the first preset brightness. The brightness of the screens on the two sides of the driver is automatically adjusted according to the face orientation of the driver, so that the situation that the screens are always on in the driving process and disturb the sight of the driver is avoided, and driving safety is improved.
Description
technical field [0001] The invention relates to the technical field of automobile control systems, in particular to a method and device for intelligently adjusting brightness of automobile electronic exterior mirrors. Background technique [0002] At present, electronic exterior mirrors are about to be widely used in automobiles. Electronic exterior mirrors usually include two high-definition cameras installed on the left and right sides of the car, and two 5-inch to 8-inch cameras installed inside the car. The screen, the screen in the car can be a traditional TFT (Thin Film Transistor, Thin Film Transistor) screen, or an OLED (Organic Light-Emitting Diode, organic laser display) screen. Both screens will emit brightness. When the screen is always on when driving at night, the screen image will be reflected on the front windshield or window glass, thereby interfering with the driver's sight, resulting in blindness in front vision, and affecting driving safety.
